How to extend Snackbar in android (Kotlin)

Question

I want to create a class which extends Snackbar but I couldn't find the constructor in the Google documentation. How should I add the constructor to the class:

import com.google.android.material.snackbar.Snackbar

class MySnackbar : Snackbar { 
    // Error: need a constructor
}

What do you want to add or change? – Gabriele Mariotti Jan 30 '20 at 07:34 — Gabriele Mariotti, Jan 30 '20 at 07:34

SnackBar is final class and thus cannot be inherited. One way is to access SnackBar's view (snackbar.getView()) and modify the view as per your need.

Snakbar is a final class and its not inherited but you can modify the view of snackbar.

You can create secondary constructor, Use below code for Kotlin.

class MyCustomSeekBar : AppCompatSeekBar {
    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)
}

Hope it helps you.

I need it for Snakbar not Seekbar. These constructors works for Seekbar, TextView, EditText, ... but not Snakbar. – Payam Roozbahani Fard Jan 30 '20 at 06:46
